Add support for ordered UUID's

[wouterdijkstra]

Added a little config option to use ordered UUID's instead of UUIDv4's.
Added a link to an article about (security) differences/advantages in the README as well.

This is a first for me, hope I'm doing things right! 😬

I'd like to keep this package very simple.

Would there be any downsides of using ordered uuids by default?

[wouterdijkstra]

First: There's the security argument; covered here.

It'd conclude the difference is negligible.

Second; ordered UUID's theoretically 'expose' the timestamp the record was created. This also means they're sortable by default, though.

Personally, for the goal of this package I'd say there are no downsides.
